Can't load more than 50 Pattern markers
Do you want to request a feature or report a bug? Bug/Issue
What is the current behavior?
I am using AR.js with multiple patterns, each one for a different 3D structure. Everything work perfectly when I have approx. 50 structures, then I add more patterns and it does not work.
The following errors appear:
[error] loadMarker(): Error loading pattern file /marker_50. [error] ARToolKitJS(): Unable to set up AR marker. [error] Out of memory!!
Here is part of my HTML file:

If this abort() is unexpected, build with -s ASSERTIONS=1 which can give more information.
Probably it reach the reach the maximum amount of memory allowed? Maybe you could recompile Jsartoolkit5 with a higher values, tweaking this value: https://github.com/kalwalt/jsartoolkit5/blob/244b2b23286403e78fa24805b34509dc5a88052f/tools/makem.js#L30
@kalwalt after changing the the line and building the project using docker will work on NFT markers? or should i need to change any parameters for making it to work on NFT?

@ragavendranbala I never tried, just try to re-build jsartoolkit5 with that increased memory option and replace the lib.
To @meizano @henriquefer i think that is not a memory issue. There is a limit of 50 Pattern markers https://github.com/artoolkitx/artoolkit5/blob/5bf0b671ff16ead527b9b892e6aeb1a2771f97be/include/AR/arConfig.h#L82 if you want to try you can re-build the libs with a higher value. Hope that helps.
@ragavendranbala this issue has nothing to do with NFT. :slightly_smiling_face:
Did anyone find the workaround beside of rebuilding lib? I tried to rebuild but it's painful. Docker is not working for me.
